An experimental setup was built to use a TSI Scanning Mobility Particle Sizer (SMPS, model 3936) instrument to investigate the time resolved evolution of particles from the ozonolysis of a-pinene and related compounds. This apparatus was characterised using the reaction of a-pinene with ozone. The time profile of aerosol mass was used to determine a value for the rate constant of k, = 9.48 X 10.17 cm3 molecule-1 S-1, which is within 5% of a recently recommended literature value. The dependence of the physical properties of the aerosol on some starting conditions was examined, and the dependence of aerosol yield on mass load examined. The particularly large effect of the nature of the OH radical scavenger on the particle number concentration was noted.
